3303i LATCH.

Application filed April 24, i922. Serial No. 556,336.

To all whom it mag/ cof/z cem.'

Be it known that I, JOHN FEITEN, a citi- Zen or" the United States ofAmerica, residing at Detroit, in the county of layne and State ofMichigan, have invented certain new and useful Improvements in BoxLatches, of which the following is a specification, reference being hadtherein to the accompanying drawings.

rlhis invention relates to box latches and more particularly to a latchfor a box or cabinet intended for display uses.

It is the object of the invention to provide a latch for a box orcabinet, which latch will have provision for positively holdino' thesame in operative position during shipment of the box.

A further object is to provide a latch for a box or cabinet that willac-t as a reinforcement for the corner of the box which it engages.

In the drawings Figure 1 is a perspective view showing the closedposition of the latch;

Figure 2 is a similar view showing the latch released and the closurecontrolled by the latch partly opened;

Figure 3 is an end view of a display cabinet to which the latch isparticularly applicable.

In these views the reference character A designates the body of a box orcabinet, and B a closure for said cabinet forming the front thereof andhinged at its top thereto, as indicated at B. The improved latchcomprises a member C rigidly carried by the body of a box, and a pivotalmember D detachably engageable withthe part C and mounted adjacent thefree edge of the closure B. The member C has the nature of a sheet metalplate. which is nailed or otherwise secured to an end face of the box A,and has marginal portions C and C2, bent to respectively overlap thefront and bottom of the box and nailed thereto. Thus said plate stronglyreinforces the corner portion of the box to which it is secured. Themember D is likewise formed of sheet metal and has its upper end pivotedupon the closure B by means of a hinge or rivet E. E is a return-benttongue laterally projecting from the lower end portion of the member D,said tongue E being rear- `wardly bent so as to overlap the forward edgeportion of the plate C. In one pivotal position of the member D, thefree end portion E2 of the tongue E is adapted to snugly engage withinan upwardly elongated slot F formed in the front marginal portion of theplate C. 'lhus when the latch member D occupies the described position,the closure B is secured in its closed position. lt is important duringshipment of the box or cabinet A, to maintain the closure thereofpositively closed as the contents of the box or cabinet are thenproperly protected` and the closure may not be easily broken. To insureagainst opening of the closure through accidental shifting of the latchmember D, provision is made for locking said latch member in its latchedposition. Thus in the free end portion of said member there is formed aslot Gr extending in a substantially circumferential relation to thepivot E. Adjacent one end portion of said slot, the member D isindented, asindicated at G and in the latched position of said member,the head of a screw H passing through said slotinto the closure Bengages within the depression G locking the member D against pivotalmovement. Obviously this locking means is of a very positive nature,since a screw driver must be used and the screw H must be turned outsuficiently to displace the head of the screw from the depression Gbefore unlatching of the closure may be effected. lt will be evidentthat subsequent to a sufficient outward adjustment of the screw H, themember D may be swung upon the pivot E, as shown in Figure 2, so as towithdraw the tongue E? from the slot F, thus leaving the closure free tobe opened.

That l claim as my invention is l. The combination with a receptacle,having a closure, of a latch for said closure comprising a memberadjustable upon the closure, and a co-acting member secured to one faceof the receptacle, and having a portion overlapping and secured toanother face thereof.

2. rl`he combination with a receptacle, having a closure, of a latchcomprising a pair of co-acting sheet metal members, one of which ispivoted on said closure, and the other rigidly secured to the body ofthe receptacle reinforcing a joint between transverse faces thereof.

8. The combination with a receptacle, having a closure, of a latchcomprising a pair of co-acting members, one of which is rigidly securedto the body of the receptacle,

and the other adjustable upon the closure thereon, and a screw the headof which engages the latter member in its closed position to look thesame.

4. The Combination With a receptacle, having a closure7 ot a latchcomprising a pair of sheet metal members, one of which is secured to at'aee ont Vsaid receptacle transverse to said closuree and is formedwith a slot7 the other latch member being' pivoted upon the front ofsaid elosure and having a laterally projecting tongue rear* Wardlyreturn-bent to engage the said slot.

5. The Combination with a reeeQtaele, having a closure7 ot a latchcomprising a pair of co-aeting members, respectively mounted upon thebody ot the receptacle,

and upon said closure, rthe latter being piveted and 'formed With a Slotand with an indentation marginal to said slot, and a screw entering theclosure through said slot hau/'ing its head adjustable into or out otsaid indentation through turning ot said screw to lock or unlock thelatch member.

G. The Combination with a receptacle having a closure, oli a latcheomprisin@` an element rigidly secured to the body of said receptacleand. reinforcing Vthe corners thereof5 and an adjustable 'element uponthe closure and engageable with the element aforesaid to secure saidClosure in Closedv position.

In testimony whereof l attix my signature.
